1. A lost motion mechanism, comprising:
a castellation device, comprising:
a casing, comprising:
a first linear slot; and
a second linear slot extending perpendicular to the first linear slot;
an upper castellation disposed in the casing, the upper castellation comprising:
an upper body;
spaced upper teeth extending down from the upper body, the spaced upper teeth separated from each other via respective upper gaps; and
an actuation peg extending out from the upper body into the first linear slot;
a lower castellation disposed in the casing, the lower castellation comprising:
a lower body;
spaced lower teeth extending up from the lower body, the spaced lower teeth separated from each other via respective lower gaps; and
an anti-rotation peg extending out from the lower body into the second linear slot,
wherein the second linear slot is configured to guide the anti-rotation peg in a direction perpendicular to the first linear slot.
