ABSTRACT:
A selectively-operable drive device for drive action including a drive input member to put drive into the device, a drive output member to supply drive action from the device, the input and output members being electrically isolatingly spaced, the device being selectively operable to put the input member and output member into driving relation by electric field electrodes on the input and output members and between the spaced members a quantity of electric field responsive fluid subject, on energisation in operation, to an electric field between the electrodes, the output member being of material of lower density than the input member and the output member having a lower mechanical time constant than the input member.
