1. A damped isolation pulley comprising:
a hub that is adapted to be mounted to a crankshaft of an internal combustion engine;
a pulley disposed concentrically about the hub;
an isolation spring coupling the pulley to the hub;
a torsional vibration damper rotationally coupled to the hub and rotationally decoupled from the pulley; and
an electro-adhesive clutch having a clutch input member that is coupled to the pulley, the electro-adhesive clutch being selectively operable for forming an alternate torque path between the pulley and the hub that does not include the isolation spring;
wherein the electro-adhesive clutch comprises a set of discrete electro-adhesive clutch segments having a first clutch segment, which is coupled for rotation with the pulley, and a second clutch segment, which is coupled for rotation with the hub; and
wherein the first clutch segment is disposed concentrically about the second clutch segment.
