direct coupling

[də¦rekt ′kəp·liŋ]
(electricity)
Coupling of two circuits by means of a non-frequency-sensitive device, such as a wire, resistor, or battery, so both direct and alternating current can flow through the coupling path.
(mechanical engineering)
The direct connection of the shaft of a prime mover (such as a motor) to the shaft of a rotating mechanism (such as a pump or compressor).

Direct coupling can be used to great effect (this is the "buzz me" technique when, for example, a vessel is grasped with a tissue forceps and then coagulated by touching the forceps with an activated electrode), but when it happens unintentionally, the result maybe catastrophic.

In fact, he enacts sculptural vignettes of "dead nature" through his recurring use of real fruits and vegetables, in works ranging in form from an ornate arrangement of bananas, pears, and apples whose decay is arrested by a viscous coating of silicone (The Human Layer, 1999) to a more brutally direct coupling of half of a pear and apple, screwed together and simply hung from a nylon cord (Untitled, 2000).
Two unique features: direct coupling to the engine flywheel enhances compactness and increases reliability; a double, high pressure oil bath mechanical seal designed with solid silicon carbide faces allows the pump to run dry indefinitely without damage.
Metrology applications require direct coupling of the array voltage to the calibration instrument with no common mode voltage.

In addition, Hagelstein summons a series of lattice vibrations and energy-flow mechanisms to explain, among other things, how electrolytic cells using palladium electrodes and heavy water might greatly enhance the negligible background rate of fusion and why "the direct coupling of coherent fusion energy into electrical energy with some efficiency seems to be likely.
