1. A spline joint to be used in a system having a casing or a screen comprising:
a box having a hollow cylindrical body, the hollow cylindrical body having an inner surface and a distal end, the distal end having an arcuate shoulder extending into a bore defined by the hollow cylindrical body toward a central longitudinal axis of the hollow cylindrical body of the box, the inner surface having a plurality of grooves defined into the inner surface of the hollow cylindrical body and a plurality of slots defining apertures through the hollow cylindrical body from the inner surface;
a pin configured to be received by the box, the pin having a hollow cylindrical body, the hollow cylindrical body of the pin having an outer surface and a distal end, the distal end having an arcuate shoulder extending outward of the outer surface in a direction away from a central longitudinal axis of the hollow cylindrical body of the pin, the outer surface having a plurality of grooves and a slot;
a plurality of splines configured to be received by a first set of grooves of the plurality of grooves of the box and the plurality of grooves of the pin, the plurality of splines insertable between the first set of grooves of the box and the first set of grooves of the pin through a first set of slots of the plurality of slots of the box to join the box and the pin; and
a key configured to be received by a second slot of the plurality of slots of the box and attached to the shoulder or a slot of the pin to prevent rotation of the pin and the box relative to each other.
