Abstract
A shaft subject to orbiting motion as it is driven in rotation is directly connected to the prime mover driving the shaft so that the prime mover follows the orbiting motion of the shaft. The housing associated with the prime mover is connected to a fixed structure through a universal coupling, which may be a gimbal, capable of preventing the housing from rotating relative to the fixed structure while permitting it to follow the orbiting motion of the shaft.
