Abstract
An eddy current coupling has telescoping input (12) and output (18) shafts to form a shunt (72, 74, 76) for the magnetic flux (78a) of the coupling around a bearing (66) between the shafts. This avoids the increased friction and heating effects and the magnetization of the bearing occurring when the bearing is exposed to the flux.
