A torque transmission device includes a shaft which has shaft teeth around its outer circumference, a hub which has hub teeth on an inner circumference, wherein the hub is arranged on the shaft in such a way that the shaft teeth and the hub teeth mesh with one another in order to transmit torque. The torque transmission device furthermore includes at least one spring element which passes entirely through the hub and is supported on the shaft and the hub and exerts a spring force on the hub and the shaft, wherein at least a component of the spring force is directed in such a way that around the entire circumference of the shaft and hub adjacent flanks of the shaft teeth and the hub teeth are pushed together.

Provided is a touch pen holder unit for holding a touch pen to prevent loss and, more particularly, a touch pen holder unit capable of fastening a touch pen easily and firmly. The touch pen holder unit includes: a wire having a locking part at an end thereof; and a body having a first locking groove and a second locking groove, in which the locking part of the wire and a head of a touch pen are respectively seated and locked at opposite sides thereof.

Spline joints and methods of installing the same. A spline joint may include a box and a pin each having a hollow cylindrical body. The pin may be received by the box. The spline joint may further include splines received by a first set of grooves of the box and grooves of the pin. The splines may be insertable between the first set of grooves through a first set of slots of the box to join the box and the pin. The spline joint may further include at least one O-ring to be received by a second set of grooves of the box to create a seal between the box and the pin. The spline joint may further include a key configured to be received by a second slot of the box and installed in a slot of the pin.
