Claim 0:
1. A coupling device for coupling a rotary actuator to a 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 rotatable 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.
