But I suspect that the gas flow in the propeller turbine only swirls against the exhaust -- don't think there are any stators in that area -- until corrected
You may well be correct about there being no stators after the propeller (output) turbine, but if the engine makes the turbine spin, and you absorb this torque in the propeller (or any load), then the opposite torque must be applied to the engine mounts, less a fraction for the swirl still left in the exhaust gases.
As interesting as this is, it is moving away from the original post about torque affects on the airframe from a single turbo-prop as opposed to a single piston.
