    Abstract: A torque responsive apparatus for controlling a fluid actuated control device includes a first shaft connected to a drive motor and a second shaft connected to the first shaft through a coupling device that controls fluid pressure in a hydraulic control system whereby torque delivered to the coupling device effects shifting of the coupling member to vary the size of an opening through which a control fluid is being passed whereby a change in fluid pressure will result which is proportional to the torque of the first shaft.
