An improved, torque cushioned compressor clutch supports the armature on a hard plastic molded disk, the inner edge of which closely pilots on, but is not directly attached to, a cylindrical surface of a drive shaft mounted central hub. Instead, the outer face of the disk, near the inner edge, is abutted with an axially inwardly facing shoulder, which keeps it from pulling axially off of the hub. A softer elastomer overmold adheres to both sides of the harder support disk, adhering to the hub as well, but not adhering to the interface between the disk inner edge and hub. Therefore, when the clutch engages, the disk is free to turn on the hub, at least as far as the "wind up" limit of the elastomer allows, cushioning the engagement shock. However, during operation, the close fit of the disk on the hub prevents radial whirl.
