Isolating Decoupler

An isolating decoupler comprising:

• a shaft having a threaded inner surface;
• a pulley journalled to the shaft on a bearing assembly, the bearing assembly comprising a bearing carrier and a bearing;
• the bearing carrier threadably engaged with the threaded inner surface;
• a one-way clutch engaged with the shaft;
• a torsion spring engaged between the one-way clutch and the pulley;
• and
• the torsion spring having an end welded to the one-way clutch and having another end welded to the pulley.
