A tensioner is a device that applies force to maintain tension. They are used to reduce slack created in chain drive and belt drive mechanisms.

Idler
Another sprocket or pulley is used to add tension to the chain or belt. It does not add any torque to the system and freely spins.
Guide
Chain guides use a durable low friction material to squeeze the chain into tension. This is most commonly used for timing chains (kept lubricated inside the engine) and sometimes on bicycles[1].
Eccentric

can be done w coarse/fine pitch instead of handedness (i completely forgot what the name is for this kind of turnbuckle, but they have less wear/play [citation needed] but allow a smaller range of motion)
