1. A torsional and vibration damping coupling for a power transmission for directly coupling a drive shaft for simultaneous rotation with an engine output shaft that experiences torsional vibrations comprising a first coupling member fixed for rotation directly to said engine output shaft and rotating simultaneously therewith, an inertial member coupled for rotation with and carried by said first coupling member and torsionally rotatably relative to said first coupling member for absorbing torsional vibrations of said engine output shaft, a second coupling member affixed directly for rotation with aid drive shaft, an elastic coupling means for simultaneously coupling said first and said second coupling members for rotation and for permitting limited relative rotation between said first and said second coupling members for absorbing torque variations in said engine output shaft.
