Actuation devices for well tools

An actuation device for well operations, comprising:

• a tubular body including a plurality of key slots;
• a threaded shaft positioned within the tubular body that rotates relative to the tubular body and is fixed axially relative to the tubular body;
• an actuator disposed within the tubular body that is moveable axially relative to the tubular body, wherein the actuator includes a ramp portion and a threaded neck portion that engages with the threaded shaft such that when the threaded shaft rotates, the actuator moves axially relative to the tubular body;
• and
• a plurality of keys recessed within the tubular body, each key disposed in one of the plurality of key slots and in operative communication with the ramp portion such that as the actuator moves axially relative to the tubular body toward the plurality of keys, each key is urged radially outwardly from the tubular body;
• wherein each key includes a post extending radially inward therefrom.
