Restricting Ball Spin (Ball Rolling Physics)

I am creating a ball rolling game and I’m having a problem with the ball radically spinning out of control. The longer I hold a key in a certain direction, the worse the spin will get.

This is how the Player Pawn is set up -

I’m pretty much just looking for a solution that will reduce the spin, any help on the matter will be highly appreciated.

The longer you are holding the key the more torque you are adding to it so the more crazy it gets.
Quick answer: I would propose adding a branch block and if torque is less than x then add more torque… else do nothing. That way you can still ramp up to x torque but not go past it.
