Abstract

See full text

The present invention provides a coupling device for coupling a rotary actuator to a mechanical device having a rotatable shaft. The coupling device comprises a spring return module with a first rotatable coupling configured to engage a first portion of the shaft, and a spring engaged with the first rotatable coupling, wherein the first rotatable coupling is rotatable about a rotation axis, and wherein rotation of the rotatable coupling about the rotation axis in a first direction causes mechanical energy to be stored in the spring. The coupling device further comprises an actuator coupling module comprising a second rotatable coupling. The second rotatable coupling is configured to engage a second portion of the shaft, the second rotatable coupling being further engageable with an output of the rotary actuator. 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.
