An eddy current coupling 11 includes an input member 19, an output member 21 rotatable relative to the input member about an axis of rotation, a pole assembly 29, an inductor drum assembly 25 and a field coil 41 for coupling the input and output members. The inductor drum assembly 25 includes a generally cylindrically drum portion 27 and a radially extending drum portion 26. A heat dissipating member 71 integrally formed from a heat conductive material such as aluminum is attached to the radially extending portion 26 of the inductor drum assembly. The heat dissipating member includes heat dissipating fins 75 on one side thereof and rivet means 77 on the opposite side thereof for connecting the integrally formed heat dissipating member 71 to the radially extending portion 26 of the inductor drum assembly. The rivet means 77 act to transfer heat from the inductor drum assembly 25 to the heat dissipating member 71.
