Some of the API in missing from the documentation

Could it be a circular import dependency?

It looks like dbus_objects.object imports dbus_objects.integration, which imports dbus_objects.object again. AFAICT object only needs integration for type checking, so you could remove the import of integration and use a forward-declaration:
