Patent ID: 8277269

Claim:
A torque transmitting device for a marine propulsion system, the torque transmitting device comprising: an adapter extending along an axis of rotation, the adapter comprising a first portion that engages in torque-transmitting relation with a propulsor shaft of the marine propulsion system so that rotation of the propulsor shaft about the axis of rotation causes synchronous rotation of the first portion about the axis of rotation and a second portion that engages in torque-transmitting relation with a propulsor hub of the marine propulsion system so that rotation of the second portion about the axis of rotation causes synchronous rotation of the propulsor hub about the axis of rotation, the second portion connected to the first portion by a plurality of elongated torsional members that are integrally attached to at least one of the first and second portions, wherein the elongated torsional members allow the first portion and second portion to rotate relative to each other about the axis of rotation while remaining connected together by the elongated torsional members, wherein the first portion is rotatable relative to the propulsor hub.
