Torque devices for use with intravascular devices and associated systems and methods are disclosed. In some embodiments, a torque device for use with an intravascular device includes a first component having a body defining a tapered opening for receiving a proximal portion of the intravascular device, a first arm extending from the body, and a second arm extending from the body; and a second component movably coupled to the first component, wherein the second component is movable relative to the first component between an open position where the torque device is configured to slidably receive the proximal portion of the flexible elongate member between the first and second arms of the first component and a closed position where the torque device fixedly engages the proximal portion of the flexible elongate member between first and second arms of the first component.
