Claim:
1. An apparatus comprising: a load; a first armature; a first lever mechanically coupling the first armature and the load and configured such that motion of the first armature causes the first lever to pivot about a first pivot axis; a second armature; a second lever mechanically coupling the second armature and the load and configured such that motion of the second armature causes the second lever to pivot about a second pivot axis; at least one stator for creating magnetic flux for the first and second armatures to interact with, thereby to drive motion of the load; and a coupling mechanism coupling the first lever and the second lever, wherein the coupling mechanism is arranged to encourage common mode oscillation of the first and second levers and inhibit differential mode oscillation of the first and second levers, thereby to inhibit rocking of the load, wherein the coupling mechanism couples the first and second levers via the first and second armatures.
