A key includes a body shaped to fit loosely in a groove along the length of the outer surface of the shaft. The key further includes a force-applying member disposed on the body for applying a force against the shaft and pressing the body against the sprocket to lock it in position on the shaft. The sprocket can further have a slot through its central bore wall in which part of the key can reside to rotate the drive member with the shaft.
