Abstract
A coupling device for high speed rotation applications comprised of a first member about a longitudinal axis having a collar integrally attached to a solid base and a second member about a longitudinal axis having a sleeve which is receivable within the collar. When the first and second members are rotated the sleeve expands within the collar to minimize or eliminate any clearance that may exist between the sleeve and collar. The coupling device may, among other applications, be utilized for machine tools such as milling cutters.
