Abstract
An apparatus includes a first shaft member including a first material and having a first shaft axis, a first distal end having a first diameter, and a first proximate end, and a second shaft member including a second material different from the first material, and having a second shaft axis, a second proximate end having a second diameter, and a second distal end. A joint permanently affixes the first distal end of the first shaft member to the second proximate end of the second shaft member such that the first shaft axis is aligned with the second shaft axis, where the first distal end substantially abuts the second proximate end, and wherein the first diameter is substantially identical to the second diameter. The second shaft member protrudes through a housing, the housing including a seal sealing against an outer diameter of the second shaft member.
