Abstract
A valve actuator for controlling a valve is provided. The valve actuator includes a torque transfer arrangement interposed between a return spring and a drive gear, the drive gear being biased by loading provided by the return spring. A drive coupling is interposed between the drive gear and the return spring and transfers load of the return spring to the drive gear. A torque transfer arrangement between the drive gear and drive coupling permits limited relative angular movement of the drive coupling relative to the drive gear.
