Abstract
Abstract This invention provides a flexible drive coupling mounted between a resiliently supported prime mover and a rigidly supported power take-off shaft. The prime mover in the instant application is a compressor and is situated in a hermetic enclosure so that a magnetic coupling means is provided between the flexible drive coupling powered power take-off shaft and an output so as to drive the output shaft mounted outwardly of the hermetic enclosure. This output shaft may conveniently mount a fan, belting or the like so as to receive its power from the prime mover.
