INTERLOCKING, SELF-ALIGNING AND TORQUE TRANSMITTING COUPLER ASSEMBLY, SYSTEMS AND METHODS FOR CONNECTING, INSTALLING, AND SUPPORTING FOUNDATION ELEMENTS

摘要

A self-aligning and torque transmitting coupler assembly includes an outer coupler coupled to a first shaft of and an inner coupler coupled to a second shaft. The outer coupler comprises an inner surface having primary and secondary alignment and torque transmitting features, and the inner coupler comprises an outer surface having primary and secondary alignment features. The primary and secondary alignment features are configured to interlock and facilitate alignment of the first and second shafts along a common axis in an exemplary application of a foundation support system.
