6. A magnetically-coupled torque-assist device, comprising:
a rotor including a plurality of movable magnets arranged within or on the rotor, the rotor being configured to rotate about an axis of rotation;
a stator including a plurality of stationary magnets arranged within or on the stator, the stator being configured to rotate about the axis of rotation;
wherein the plurality of movable magnets and the plurality of stationary magnets are permanent magnets;
wherein the plurality of movable magnets are square magnets or rectangular magnets;
wherein at least one movable magnet of the plurality of movable magnets defines a first axis bisecting the movable magnet through a first pair of edges of the movable magnet and a second axis bisecting the movable magnet through a second pair of edges of the movable magnet;
wherein the first axis and the second axis do not intersect the axis of rotation;
wherein the first axis of the at least one movable magnet is parallel to a first rotor axis bisecting the rotor, and the second axis of the at least one movable magnet is parallel to a second rotor axis bisecting the rotor;
wherein the first rotor axis and the second rotor axis both intersect the axis of rotation and are perpendicular to each other; and
wherein the at least one movable magnet on the rotor is the same shape as a corresponding at least one stationary magnet on the stator, such that all edges of the at one movable magnet align axially with all edges of the corresponding at least one stationary magnet of the stator in at least one rotational position of the rotor and the stator.
