An aircraft propeller drive system for an aircraft is disclosed. The aircraft has a propeller driven by an intermittent combustion internal combustion engine via the propeller drive system. The propeller drive system has: a torsion bar having a first end and a second end opposite the first end, the first end being adapted to be operatively connected to and driven by the engine about a torsion axis, the second end being rotatable relative to the first end about the torsion axis by a torsion angle; an output shaft rotationally fixedly connected to and driven by the second end of the torsion bar, the output shaft being adapted for being connected to the propeller; and a hydraulic damper operatively connected between the output shaft and the first end of the torsion bar to dampen at least some variations in torsion angle of the torsion bar.
