An isolator decoupler comprising a shaft, a pulley journalled to the shaft, a clutch carrier journalled to the shaft through a one-way clutch, a torsion spring engaged between the pulley and the clutch carrier, the torsion spring loadable in an unwinding direction, the torsion spring and the pulley having a predetermined clearance between a torsion spring outside diameter surface and a pulley inside diameter surface, and whereby the torsion spring outside diameter surface and a pulley inside diameter surface come into a progressive frictional engagement by torque load dependent radial expansion of the torsion spring.
