A surgical system includes a firing rod configured to be translated to deploy surgical staples during a firing stroke and a microcontroller configured to adjust firing rod velocity by pausing movement of the firing rod for a predefined period of time when the microcontroller detects a current draw by a motor driving the firing rod that exceeds a predefined threshold value. After the pause, the firing stroke can be resumed and if the current draw increase is less than the threshold value, the microcontroller can proceed cause the motor to drive the firing rod through the firing stroke without adjusting the velocity of the firing element.

A power transmission device for transmitting power to a rotor of an electric machine is disclosed, and may include a rotor module shaped and a stator module. The rotor module may have at least two rotor slip disks which are ring-shaped. The stator module may have at least two counter slip disks which are ring-shaped. The central axes of the counter slip disks may run coaxially to one another and to the spin axis. The center diameter of a first counter slip disk corresponds to the center diameter of the first rotor slip disk and the center diameter of a second counter slip disk corresponds to the center diameter of the second rotor slip disk. The stator element may include at least one control element configured to press the counter slip disks at least temporarily in the direction of the spin axis against the rotor slip disks. An electric machine and a method for adjusting a power transmission device during operation of an electric machine is also disclosed.
