Claim 10:
11. An apparatus comprising:
a mechanical device having a rotatable shaft;
a rotary actuator; and
a coupling device for coupling the rotary actuator to the mechanical device having a rotatable shaft wherein the rotatable shaft is rotatable to control an operational state of the mechanical device, the coupling device comprising:
a spring return module, the spring return module comprising:
a first rotatable coupling configured to engage a first portion of the rotatable shaft;
a spring engaged with the first rotatable coupling, wherein the first rotatable coupling is rotatable about a rotation axis, and wherein rotation of the first rotatable coupling about the rotation axis in a first direction causes mechanical energy to be stored in the spring; and
an actuator coupling module comprising a second rotatable coupling, wherein the second rotatable coupling comprises a channel configured to receive and engage a second, distal end portion of the shaft, the second rotatable coupling having a further coupling part configured to engage an output of the rotary actuator, wherein the channel and the further coupling part are arranged on opposite sides of the second rotatable coupling; and
 wherein the second rotatable coupling is rotatable about the rotation axis, the second rotatable coupling being rotatable relative to the first rotatable coupling about the rotation axis;, wherein the first portion of the rotatable shaft is engageable in the first rotatable coupling, and the second portion of the rotatable shaft is engageable in the second rotatable coupling; and
wherein the output of the rotary actuator is engageable with the second rotatable coupling to apply a torque about the rotation axis to the second rotatable coupling.
