Abstract
In an aspect, a clutched device is provided, including a hub, a pulley and a hub drive clutch. The hub defines an axis and is connectable to a rotatable shaft of a rotary device. The pulley is rotatable relative to the hub and is engageable with an endless drive member. The hub drive clutch is a wrap spring clutch and is controllable to operatively connect the pulley to the hub for driving the hub in a first rotational direction. An isolation spring is provided and operatively connects the hub to the pulley when the hub drives the pulley in the first rotational direction. Optionally, a pulley overrun clutch is provided and permits the pulley to overrun the hub in the first rotational direction.
