In order to alter the frequency response characteristics of the torsional resonances of an electromagnetic rotary actuator, damped couplings are provided to transmit the forces between the moving coil of the actuator and an integral load support table. The couplings are bushes, set into a coil support former, through which the former is bolted to the load support table. Each bush comprises concentric metal sleeves with a trapped layer of elastomer in between.
