Abstract : The present invention relates to a damped actuator linkage for use on an underwater vehicle. The linkage includes a first linkage member connected to an actuator for providing a torsional force, a second linkage member connected to a utility device, and a layer of non-metallic material interposed between the first and second linkage members to reduce the transmission of noise and the attenuation of vibrations. The non-metalic material layer may be a layer of polyurethane material or a layer of silicone compound. This layer is preferable cast in concentric arrangement between the two linkage members.
