The Sonic Screwdriver from Doctor Who, with many different models and functions.

Each basic Sonic Screwdriver comes in green and blue, and has 3 modes:

Activate Block
Deactivate Block
Wrench Mode

Upgrading to a red Advanced Sonic Screwdriver unlocks Scanning mode, and allows blocks to be activated through walls.

Scanning mode can tell you:

What type of entity are you looking at?
What is their health?
What are the potion effects acting on them?
It can also make a block invisible to look for secrets.

Right click on something to use the Screwdriver, and right click while sneaking or on the air to change modes. To activate a block that has it's own right click function, such as a dispenser or repeater, right click while sneaking.

Wrench mode can rotate many kinds of blocks, from dispensers and repeaters, to stairs, logs, and more. Hold alt while rotating to go the opposite direction. When rotating a block that can face any direction, it will rotate around the side that you click on, or if you click the front it will just do a 180. Thanks to the Wrenchable api, signs and banners can also be rotated while sneaking, and slabs can be flipped over.

Wrench mode can also be used on any other blocks compatible with Wrenchable

There is also a Sonic Blaster, that can open a 3x3 gap in a wall to walk through. The wall will be restored after a few seconds, or if any part of it is clicked.

Activate-able blocks include:

Iron Door
Iron Trapdoor
Redstone Lamp
Dropper
Dispenser
Piston (activate creates a 2 tick pulse, deactivate is 1 tick)

Hope you enjoy!
