ABSTRACT:
The invention is directed to a fluid friction coupling which includes a drive shaft made of steel and a drive disc made of an aluminum alloy. A coupling housing defines a work space in which the drive disc is disposed. The drive disc includes a hub defining an internal thread and the drive shaft has an end lug defining an outer thread. The drive shaft and hub are threadably engaged and tightened with respect to each other so as to cause the threads to conjointly define a thread joint which is plastically deformed to provide a permanent joint between the drive disc and the drive shaft.
