Torque devices, systems, and methods are disclosed. In some embodiments, a torque device includes a body having a proximal portion, a distal portion, and a longitudinal axis. The body includes a slot extending along a length of the body parallel to the longitudinal axis. The slot extends from an exterior surface of the body to an interior surface of the body. The slot is sized and shaped to receive a flexible elongate member. The body includes an opening extending through the body perpendicular to the longitudinal axis and in communication with the slot. The torque device includes a closing mechanism movably coupled to the body. The closing mechanism is movable within the opening of the body between an open position that allows the flexible elongate member to be inserted into the slot and a locked position that fixedly secures the flexible elongate member to the torque device.
