Abstract: Apparatuses and methods consistent with the present inventive concept relate to a clamping device which is connectable with a shaft having a longitudinal axis and four longitudinal surfaces extending in a direction parallel to the longitudinal axis, the clamping device including: a base member having two substantially perpendicular surfaces, the base member being configured to contact two adjacent longitudinal surfaces of said four longitudinal surfaces of said shaft, wherein said base member extends along the shaft in the direction parallel to the longitudinal axis; and a plurality of clamping elements, the plurality of clamping elements being coupled to said base member, wherein each of the plurality of clamping elements is flexible in a direction substantially perpendicular to the longitudinal axis of the shaft, and the plurality of clamping elements is operable to exert clamping pressure on the two adjacent longitudinal surfaces of said shaft opposing the base member.
