1. A medical instrument component comprising:
a first shaft comprising a first portion and a second portion,
a second shaft comprising a channel configured to receive the first portion of the first shaft; and
a sleeve configured to be positioned at least some of the time around the first portion of the first shaft,
wherein the first portion of the first shaft is configured to have a lower torsional strength than the second portion of the first shaft and the second shaft such that the first portion experiences torsional failure at a lower torque force than the second portion of the first shaft and the second shaft, and
wherein a positioning of the sleeve is adjustable along the first portion of the first shaft such that a torsional strength of the medical instrument component is adjustable based on the positioning of the sleeve,
wherein a positioning of the sleeve is fixed relative to the second shaft.
