Abstract

Abstract A coupling structure releasably attaches a plurality of transmission members to each other. Non-vibratory structures hold a second end of the first transmission member in contact with a first end of the second member. A method including the steps of providing a first non-vibratory structure carrying the first transmission member, and providing a second non-vibratory structure carrying the second transmission member. The method also includes the steps of attaching the first non-vibratory structure to the second non-vibratory structure to hold a coupling end of the first transmission rod in contact with a coupling end of the second transmission rod without the use of a threaded connection between the first and second components.
