1. A method of operating a drive system for driving a component of a medical instrument, the method comprising:
bringing a first rotatable element of the drive system into contact with a second rotatable element of the drive system without restricting rotation of the first rotatable element relative to the second rotatable element, the second rotatable element being shaped to engage the first rotatable element, and the second rotatable element being operably coupled to actuate the component:
applying an engagement force to create a frictional engagement between the first rotatable element and the second rotatable element without actuating the component; and
operating the drive system to actuate the component, the operating comprising transferring torque via the frictional engagement between the first rotatable element and the second rotatable element.
