The books, at least the ones I read many years ago, used to define "torque" as a collective term that included the twisting force of the engine, prop factor and the spiral prop blast.
That's part of the problem...The FAA of all orgs (but then again it's a govt org) made the same mistake in the "official" pub (forgot name of it) that all instructors had to know fwd and back. Dumb Dumb Dumb
