Abstract
A torque transmitting device for use in conjunction with a marine propulsion system provides an adapter that is attached in torque transmitting relation with a propulsor shaft for rotation about a central axis of rotation. The first insert portion is attached in torque transmitting relation with the adapter and a second insert portion is attached in torque transmitting relation with a hub of the propulsor hub which can be a marine propeller or an impeller. A third insert portion is connected between the first and second insert portions and is resilient in order to allow the first and second insert portions to rotate relative to each other about the central axis of rotation. The adapter is shaped to prevent compression of the first, second, and third insert portions in a direction parallel to the central axis of rotation. The relative shapes of the various components and the resilience of the third insert portion, which can be a plurality of titanium rods, provides significant compliance of the device under low torque magnitudes, but at higher torque magnitudes it provides a significantly decreased compliance to facilitate torque transfer between a propulsor shaft and the propulsor hub.
