Okay have learnt alot about torque in general by getting help here, so I thought I'd just a ask a liiittle more about what wonders me.

Because I can see what motivates the definition of torque mathematically but as said earlier still find it hard to understand in terms of other quantities from mechanics such as force, energy etc. - maybe torque isn't something you understand like force isn't really something you understand...?

Nevertheless I got a good intuition for it using energy considerations but still don't quite get it in the static case.
I've narrowed my search about what I basically don't get to the following:
When you exert a force on an object you would expect it to somehow to transmit between the internal parts of the objects to a series of small forces but alle these small forces can always be traced back to the net force. So the same force will transmit between the small objects of the body in the case where u apply a force in a radius of r and 2r from the rotational axis. If this is true, what is it then that makes the internal forces in the 2nd case more effective at rotation the object?

It's the same thing that makes a projected picture bigger the further away the screen is.
