A rotary valve includes a valve shaft coupled to a rotary valve element. The valve shaft defines an axis and is rotatable thereabout. The valve further comprises a rotary position sensor and a coupling rotationally coupling the valve shaft and the sensor. A wrenching arm is rotationally coupled to the valve shaft, and extends radially outwardly of the axis for attachment of a wrenching tool thereto. The coupling is axially between the rotary position sensor and the wrenching arm.
