The wheel that turns a thousand tons with one decisive hand.

means The steering apparatus of a ship — the wheel or tiller used to control its course — and, by extension, any position of leadership or control.

from From Old English 'helma,' meaning a tiller or rudder handle. It's likely related to 'helve,' the handle of an axe or tool — both rooted in the idea of a shaft you grip to direct something. Note that the 'helm' meaning headgear (as in helmet) is a separate Old English word, 'helm,' for a protective covering; the two look identical but steer in different directions.
