Claim Text:
1. An apparatus comprising: a state machine connected to a force management system; a first ball screw connected to a base plate configured to connect to a spacecraft, the first ball screw connected to a first power transfer device directly connected to a first movement system configured to receive a first command to move the first ball screw at a first rate such that the first ball screw comprises a first rate of axial movement; a second ball screw connected to the base plate and to a second power transfer device directly connected to a second movement system configured to receive a second command to move the second ball screw at a second rate such that the second ball screw comprises a second rate of axial movement, the second rate of axial movement being independent of the first rate of axial movement, such that the first power transfer device comprises a first torque limit determined independent of any intervention from any electronic control system, control law, and software application, in at least one of: the spacecraft, another spacecraft, and a combination thereof, and the second power transfer device comprises a second torque limit determined independent from: the first torque limit, the first command, and any intervention from the any electronic control system, control law, and software application.
