How to make Gamepad stick same as WASD controls

What I like:
Thumb stick all the way to the upper right (Perfectly diagonal) is the same as pressing W and D at the same time on the keyboard. This should then also work with the strength of far how you push the thumbstick in that direction.

Now I need this work for a ball rolling game with torque. The ball rolling game example is rather crude with a torque node for front and back and another torque node for left and right. Which would then mean you already get a higher strength when pressing W and D versus pressing just W. I’m also missing something that gives me the thumbstick rotation and something giving me the strength for the whole thing. Instead I only got a up and down axis and left and right axis as 2 separate things.

What would be a way to archive this?
