Abstract
In an aspect an isolation device is provided, comprising a hub that is connectable to a shaft; a pulley that is rotatable relative to the hub; at least one isolation spring positioned to transfer torque between the hub and the pulley, wherein each of the at least one isolation spring is an arcuate helical compression spring having an isolation spring axis that is arcuate; and a spring shell that is monolithic and that receives the at least one isolation spring and transfers torque between the at least one isolation spring and the pulley. The spring shell surrounds more than 180 degrees of the at least one isolation spring in a plane that is perpendicular to the isolation spring axis.
