Couplings
by HeckinChloe
With Couplings installed, opening one door, fence gate or trapdoor also opens the blocks attached to it, on Fabric for 1.18.2 – 1.20.1.
What it does
Double doors with opposing hinges swap together when one is used. Vertically stacked fence gates open as a group, and every trapdoor along the same side axis, including its opposing counterpart, follows the one that was used.
Couplings also changes how redstone reaches linked blocks. A signal strength above 7 (50%) powers all coupled blocks at once, while a weaker signal powers only the block it touches. The author describes this as a way to make block updates more responsive.
The server must run the mod, while players may add it for the same behavior, so the server is the side that depends on it. Couplings is released under the Apache License 2.0, is open source, and has public links to its source code and issue tracker. Files are published for Fabric, with 8 release versions, the latest being 1.9.4+1.20 for 1.20.1, dated 2023-07-14.

Use cases
Builds with rows of doors
Entrances built with paired doors or stacked gates can be operated with one click.
Redstone-driven setups
Signal strength decides whether a whole linked group switches or only a single block does.
Who it’s for: Builders who want grouped doors, gates and trapdoors in decorative or functional structures, and server owners who run Fabric and want the same behavior for every player.
How it compares
Fence Gate Fix is needed on the server, with the client optional, while the server alone can run it; it is released under the MIT License, is open source, and has files for 1.16 – 26.3. Better paths runs only on the server, with players needing nothing; it is open source under the GNU General Public License v3.0 only and is published for 1.20.5 – 26.3. Couplings is narrower in scope and targets only the 1.18.2 – 1.20.1 range.
