I am looking for a way to associate assemblies that contain DnnController or IServiceRouteMapper implementations 
(as shown in the code below) and module definitions (friendlyname or modulename) they are part of. 

Basically I might have a few assemblies  in a package and some of them will have these implementations (see example manifest below the code).
Is that facts exposed anywhere in module definitions and if not how to figure out what packages certain assemblies are part of.
I guess in my case there will be one type in an assembly that can register one or more assemblies that contain DnnController-s.
I know there the manifest in string format are stored in DB:
SELECT Manifest FROM Packages, but I would like to avoid manually parsing that file or using DNN to do the parsing for me.
private FindModuleDefinitions()

{
    get
    {
        List<string> locations = new List<string>();
        foreach (Type routeMapperType in GetAllServiceRouteMapperTypes())
        {
            locations.add(routeMapperType.Assembly.Location);
// How to obtain module definition that this assembly is part of? I would prefer Friendly name at this point.
        }
        return locations;
    }
}
 
 private IEnumerable<Type> GetAllServiceRouteMapperTypes(){
    return (new TypeLocator()).GetAllMatchingTypes(IsValidServiceRouteMapper);
}
 
private static bool IsValidServiceRouteMapper(Type t){
    return t != null && t.IsClass && !t.IsAbstract && t.IsVisible && typeof(IServiceRouteMapper).IsAssignableFrom(t);
}

This package definition ilustrates visually what I want to get.

<dotnetnuke type="Package" version="5.0">
  <packages>
    <package name="Connect AccountRegistrationForm" type="Module" version="01.00.00">
      <friendlyName>Connect: AccountRegistration</friendlyName>     >>>> I want to get this element based on descoverd assembly names (**) and (****) below
                                                                         using a method like one above: GetAllServiceRouteMapperTypes()
...

        <component type="Assembly">
          <assemblies>

            </assembly> 

            <assembly>
              <name>Connect.Libraries.GrouprManagement.dll</name>    >>>> doesn't contain secondDnnController or  IServiceRouteMapperimplementation
            </assembly>                                                                   (some third party library or utility class) 
          </assemblies>

        </package>

     </package>
