Adeptus Mechanicus are in the codex mod. Technically they are just a pull together of a wide range of servitor models from various mods/races, with some special vehicles added. They didn't make any models for that mod, but it is still a lot of fun because it combines models from lots of different mods, that you can't get together otherwise.
