The devil's in the wordiology and detail.

Prop torque is a bit of a misnomer but, for those who like to use the term, fine. This concept is only an effort to relate instantaneous blade drag loads to a rotating bit of machinery. That is, we are still only talking about drag acting on the disc. Whatever you might want to call the animal, it only is a measure of that which is endeavouring to slow the disc rotation - it can't cause a reverse rotation.

Both these torques are balanced out for normal operating conditions for constant RPM operation.
