The present invention provides a spring return device comprising a rotatable drive coupling configured for releasably engaging a rotatable drive part on a first side of the device and configured for releasably engaging a rotatable drive part on an opposite second side of the device. A spring is engaged with the drive coupling, and a retainer retains the spring. The drive coupling is rotatable relative to the retainer, wherein rotation of the drive coupling relative to the retainer in a first direction causes mechanical energy to be stored in the spring. The spring return device further comprises a limiter element that is arranged to rotate with the drive coupling, and one or more stopping surfaces comprising a first stopping surface arranged to abut a first limiter surface on the limiter element when the drive coupling is in a first predetermined rotational position, to thereby limit rotation of the drive coupling relative to the retainer in a second direction, the second direction being opposite to the first direction. The spring return device of the invention may facilitate reversing the direction of operation of the spring return device.
