Patent ID: 8578799

Claim:
A shaft coupling assembly comprising: a first coupling device coupled to an end of a power shaft, said first coupling device comprising a first plurality of projections extending away from said first coupling device; a second coupling device, said second coupling device comprising a second plurality of projections extending away from said second coupling device; a third coupling device disposed between said first coupling device and said second coupling device, said third coupling device comprising a first side and a second side disposed opposite to said first side, said first side of said third coupling device comprising a first media configured to matingly engage said first plurality of projections in an axial direction of said first projections, said second side of said third coupling device comprising a second media configured to matingly engage said second plurality of projections in an axial direction of said second projections; wherein said first and second pluralities of projections comprise a relatively large length to width ratio and when inserted into respective said first and second media, said first and second media displace orthogonally to the insertion direction an amount sufficient to facilitate the insertion for each individual projection while substantially preventing gross movement of all of said projections in total such that a torque applied to one of said coupling devices is transmitted through the mated projections and media; and wherein said first plurality of projections are inserted into said first media before said second plurality of projections are completely removed from said second media.
